Why did L-dopa stop working in Awakenings?
In a discovery that might turn out to be a game changer in Parkinson’s research, University of Alabama at Birmingham researchers discovered that DNA methylation causes L-DOPA to stop being effective after a few years, instead giving rise to dyskinesia — involuntary jerky movements making life even harder for patients.
What drug was used in Awakenings?
It tells the story of a fictional character, neurologist Dr. Malcolm Sayer, who is based on Sacks and played by Robin Williams. In 1969, he discovered beneficial effects of the drug L-Dopa. He administers it to catatonic patients who survived the 1917–1928 epidemic of encephalitis lethargica.
